is a systematic LP5553 power management interface （SPMI） Comply with energy reduction power consumption and low power hand management stock holdings, such as dual-core processors and DSP applications.
The LP5553 contains 2 advanced, digitally controlled variable voltages to provide an SoC step-down DC/DC converter. The device also integrates 5 programmable low-dropout, low-noise linear regulators for driving I/O, peripheral logic blocks, auxiliary system functions, and keeping memory in shutdown mode (dual-domain).
While LP5553 implements 2 non-requests through SPMI control capabilities. Operate and partner with PowerWise for LP5553 ® AVS technology compatible processor to optimize supply voltage adaptation (AVS - Adaptive Voltage Regulation) to process and temperature variations. It also supports dynamic voltage amplification (DVS) with pre-feature lookup meter frequency/voltage pairs.
